Methyl and ethyl free radicals

Methylium cation and ethyl anion

Methyl anion and ethylium cation

Methylium and ethylium cations

Low chemical reactivity of alkanes is due to strong C—C and C—H bonds

Alkanes show characteristic substitution reactions because they are saturated

Reaction of alkanes with fluorine is explosive even in dark

All of the above

${3^0} > {1^0} > {2^0}$

${1^0} > {2^0} > {3^0}$

Both 1 and 2

${3^0} > {2^0} > {1^0}$

reduction of $C{H_3}COOH$ with $HI/{P_4}$

reduction of $C{H_3}COC{H_3}$ with $HI/{P_4}$

soda lime decarboxylation of sodium propionate

hydrogenation of ethene in presence of $Ni$

The staggered conformation is more stable than the eclipsed conformation due to less torsional strain.

The eclipsed conformation is more stable than the staggered conformation due to less torsional strain.

Both conformations have the same energy.

The staggered conformation is less stable than the eclipsed conformation due to more steric strain.
